Separation Seal (Non-contacting Technology) is8648VRS

is8648VRS is a standardized non-pusher elastomer mechanical seal using patented technology, designed specifically for difficult hydrocarbon oil pipeline applications. It is designed specifically with a focus on meeting the demanding requirements of pipeline pumping station duties. Available as a single, dual pressurized or dual unpressurized arrangement, without outboard seals also incorporating the same non-pusher technology, the seal can be configured to suit both the operator and pipeline needs.

The main risk of seal failure in these applications is due to the numerous problems associated with the secondary dynamic O-ring, potentially resulting in hang up, fretting or stub sleeve wear. The unique design of the is8648VRS completely eliminates these common problems.

By allowing operation without the potential for secondary seal problems, the is8648VRS provides longevity and reliability even in the most difficult pipeline applications.

Features is8648vrs

California Residents: PROPOSITION 65 WARNING
Unique patented secondary seal technology prevents
wear to the sealing diameter and prevents secondary seal hang up
Non-compressible flexible elastomer bellows avoids fretting under pump shuttling
Robust Ear drive — primary ring incorporates optimized ear drive design for increased drive torque capability
Balanced design – balanced construction, including anti-extrusion ring, permits use in the most demanding high-pressure pipeline duties
Rotating mating ring design — enhances cooling and permits use at higher shaft speeds
Premium seal face materials — permits sealing of difficult services at high operating pressures
High-shore elastomer for lack of deformation and robust construction
Axially compact and easy to install seal head assembly
Static reverse pressure capability on the inboard seal of the dual pressurized configuration
Laser face grooved mating ring for use on flashing hydrocarbons
